[ggray]

Есть киска 4503 на супе V-10GE IOS 15.0(2)SG9 + два х2 транссивера. Проблема: не поднимается линк на х2 интерфейсах, даже лупил их ... но тож не хотят, помжите люди добрые. Вот че киса мурчит при лупе на Х2:

Низкий уровень сигнала. Случайно кабели не перепутали? (mm на single модули и т.п.)
